Hi...
In ArcGIS Pro, I can rigth-click a FeatureClass the .gdb file and select Open Table in its context menu.

When I do this, the attribute window shows the list of rows, and no FeatureLayer gets placed into the map.
This is what I want!!!
Is there a way to do this programatically? I know there is, because the application, a program, does it.
When I try to add the FeatureClass item to my custom table, Visual Studio tells me the featureClass is not a map item.
When I tried to turn the FeatureClass into a StandaloneTable,(which still puts it in the map), I get an error during creation.(co-pilot says it's because my FeatureClass is in a Dataset called __WorkContainer__ and StandaloneTable creation does not trust workspaces that look temporary. Is this really the case?

My preference is to do with my FeatureClass what the application does, but within my custom attribute table.
The table is the one from the community examples.
